One of the main protagonist of the anime series Galilei Donna. She is the youngest daughter of the Ferrari family and the creator of Galileo. There is a theory that Hozuki maybe the key to the Galileo Inheritance but nothing has been said as of yet. Hozuki is a junior high school student, and she is known for being somewhat flighty. Even if she tries something, she doesn't keep at it for very long, but science is her only strong point. She is reserved and quiet, but she is probably the most likely to take action amongst the three Ferrari sisters.
